Method:1) In a nonstick pan, heat 1 tbsp oil. Add grated ginger, chopped green chilies, finely chopped onion and sauté. Once onion is translucent, add Besan and stir until you sense nice aroma of Besan. Remove from heat and let it cool down.2) Pressure-cook Moong to 2-3 whistles. Do not overcook and remove excessive water.3) Peel boiled potato and grate it. Add Cooked Moong, fried Besan, salt, Amchoor Powder, chopped Cilantro. Mix and knead gently.4) Make patties out of the mixture. Heat a non-stick shallow pan or tawa, add 2 tbsp oil and place patties on it. Cook both sides of each patty until golden brown.5) Preheat Oven to 350 degrees F. Spread little butter and green chutney inside of Burger Buns. On the base slice of bun, place one patty, tomato and Onion slice, Cheese slice. Place other slice of burger bun.6) Bake for 6-7 minutes or until cheese melts. Serve hot with Tomato Ketchup.

Note:1) While shallow frying Patties, coat patties with some roasted semolina. It will give nice crisp to patties.2) You can add other veggies like spinach, Cabbage leaves or even lettuce.3) You can use wheat Buns, which would be more healthy than white buns4) If the mixture becomes little soggy, add some breadcrumbs or bread slice. As we have already added Besan, there should not be any problem.
